Application filed April 24, 1916. Serial No. 93,309.

v To all whom it may (om-mat:

duce the aforesaid alternating relatively Be it. known that we, JoimPAXTON I l Perry and \Vxnnnn Cmus'rornnn Arman. subjects of His Majestythe King of England, resjmctively residing at ()rowthorne,

Berkshire, l lngland, and Reading, Berk-,, shire,-llnglaml, haveinvented certain new and useful Improvements in Knocking Up Sheets andthe like, Particularly Paper Sheets, of which the following is aspecification.

This invention relates to an improved construction of knocking upmachine for carrying out the process for "iknocking up sheets of paperor the like described and claimed in the specification pfour applicationfor Letters Patent-Serial No. 873,598, filed November 23rd, 1914.

By the present invention the sheets or the like which are v piled one onthe other on a support arc;sub eeted to a series of impulses or tl-1;-,...1--ike at an angle to the plane. of the paper and also to a seriesof impulses in a direction lying in the plane or;

the paper and'toward the lay edge or edges,

by imparting preferably in sequence relatively, gradual-1y and suddenlyarrested arcuatc swinging movements to a spring mounted suppbrt on whichthe sheets lie, the direction of the relatively gradually arrestedmovement being away from the lay edge or edges and the direction of thesuddenly arrested movements being toward the lay edge or edges. Thesuddenly arrested movements in the hereinafter described embodiment arearranged to be sharp movements in relation to the gradually arrestedmovements and to be initiated suddenly.

Bud sharp and suddenly initiated movementsniay be produced at any localpart of the swing.

In an exemplarform of the invention'a support with lay fences .ismounted elasti ca l y at the corners on cylindric spiral springs so aspreferably to slope somewhat to one corner and so as to be capable ofbeing; horizontally swung with consequentflexure o'f the springmountinglSteps on the board co-act with one .or more jumping cams formed so "astopro-' gradually and suddenly arrested horizontal swinging movements tothe support. Thus a shaftrunning transversely of the ma- ('lllllO maycarry both a peripheral jumpmg cam and a crown umping cam each havlng 'agradual rise and a quick fall oil and each For the purpose ofmakingour'said invention better understood we describe with the aid ofthe accompanying drawings the exemplar machine hereinabove' referredto.

In the drawings Figure 1 is a sectional side view of the machine.

Fig. 2 a sectional front view thereof. Figs. 3 and 4 are face and edgeviews respectively'of the crown jumping .cam.

Figs. 5 and 6 are face and edge views respectively of the peripheraljumping cam.

Figs. 7 and 9 are elevation and plan views respectively of a brackethousing the bowl co-acting with the crown jumping cam, while, j

Figs.'8 and 10 are elevation" and plan views respectively of a brackethousing the bowl co-acting with the peripheral jumping cam.

Referring to. Figs. 1 and 2' the machine cplnprlses a board or supportlmounted elastically at 'the corners on cylindric spiral springs 2, sonspreferably to slope somewhat to one corner 3, to facilitate the movementof the sheets or-the like towardthis. corner which is made the laycorner, it be: ing desirable in such a case that the board unit sprinThe spring fl engage sets of" :be supported at this corner by a strongerDriven by a suitable drive 9, 9 9", a revolving shaft 8, runningtransversely of the machine and mounted in the said frames 7, this shaftcarrying a crown jumping cam 10 (Figs. 3 and 4) and a peripheral jumpingcam 11 (Figs. 5 and 6). As will be observed these cams have a gradualrise and a quick fall off. The cam 10 co-acts with. a bowl or roller 12housed in a bracket 13 (Figs. 7 and 9) fixed to and depending from theunderside'of the board or support 1. The cam 11 co-acts with a bowl orroller 14 housed in a bracket 15 (Figs. 8 and 10) also fixed to anddepending from the underside of the board 1.

Stationary fences 16 and 17 constituting the lay edges are provided onthe board 1.,

These fences are mounted on slides by means of which they may be fixedin any desired position. A movable side jogger 18 is provided coupled toa cam, 19 on the revolving shaft 8, whereby movement is imparted to saidjogger. Obviously a back movable jogger may be provided for.

Good results have been obtained with such a pair of cams giving one falloff each revolution and each timed to release its stop simultaneouslywith the other, the shaft and cams thereon revolving at 174 revolutionsa minute.- Good results have also been obtained by 180 revolutions aminute of the cam shaft and cams, the pair of cams in this case eachgiving one fall ofl each revolution, and the peripheral cam releasing at0 and the crown cam releasing at 40.

While any suitable arrangement for or mode of feeding the sheets may beemployed, one-comprising the arrangement according to our aforesaidapplication for Letters Patent conduces to the obtainment of goodresults, as the stepped-sequent and rapid individual feed, according tothis patent, has the effect that any sheet is gpickly settled down ontothe board by t e succeeding sheets without however preventing theknocking up process from leadingthe sheet to the lay edge or edgesbeforethe topweight bearing on such sheet accumulates sufficiently to countadverse to the process. Insteadof using a pair of earns, a. 6., a crownjumping cam and a peripheral jum ing cam, 21 single cam mounted to iveiagonal alternating movements of the kind referred to maybe employed.

With a. construction of machine substankept in a live condition and atthe same time to realize structura-lsimplicity and manufacturing andup-keeping economies.

What we claim is l 1. For the purpose of piling sheets 'according to theprocess herein referred to, a

machine comprising a support on which the sheets lie, a spring mountingfor said sup port adapted to permit the support to be vibrated tosubject the sheets thereon to a series of impulses at right angles totheir planes and also to a series of impulses parallel to their planessheet edge resting l'neans serving as a dressing fence in bringing saidsheets into registry, driving means. means driven from said drivingmeans and adapted to impart gradually and suddenly arrested horizontalswinging movements to the support, the direction of the graduallyarrested movements being away from the sheet cdgeffesting means, and thedirection of the suddenly arrested movements being "toward the sheetedge resting means, and

the gradually arrested movements being actual or positive graduallyarrested move ments completely dependent on the motion of said drivenmeans.

2. For the purpose of piling sheets according to the process hereinreferred to, a machine comprising a spring mounted support on which thesheets lie, sheet edge restmg means serving as a dressing fence in.brmg1ng said sheets into registry, and means comprising a stop on thesupport coacting with a jumping cam for imparting relatively graduallyand suddenly arrested horizontal swinging movements to the support,thedireetion of the gradually arrested movements being away from thesheet edge resting means and the direction of the suddenly arrestedmovements being toward the sheet edge resting means.

3. For the purpose of piling sheets according to the process hereinreferred to,a machine comprisin a' springmounted support on which thesieets lie sheet edge resting means serving as a dressing fence inbringing said sheets into registry, and ineans comprising stops on theboard eo-acting with a peripheral jumping cam. on theone hand, and acrown jumping cam on the other hand, each cam having a gradual rise anda quick fall ofl', for imparting relatively gradually and suddenlyarrested horizontal swingingmovements to the sup )ort, the di- 'rectionof the gradually arreste movements being away from the-sheet edgeresting means, and the direction of the suddenly arrested movementsbeing toward the sheet edge resting means.

4. For the purpose of piling sheets ac- I cording to the process hereinreferred to, a machine comprising a support on which the sheets lie,asprmg mounting consisting of cylindric spiral springs for said supportadapted to permit the support to be vibrated I 'to subject the sheetsthereon to a series 'of impulses at right angles to their planes and'also to a series of impulses parallel to'their planes sheet edgeresting means serving as Ldressih'g fence in-bringing sheets info thesupport and produce a' suddenly arrested registry firiving ineans, meansdriven from" return movement of the support in a' direcsmd dnving meansand adapted to first tion toward the sheet edge resting means. 10 I.bodily move said support to flex sdidsprings" In testinlony whereof, weaflix our sigma-- I? with a gradually arrestad movement comturesglete'ly dependent on the motion of said JOHN PAXTON PETTY.
